1. A non-pressure sensitive (“NPS”) module for use with a liner hanger installable within a borehole via a run-in tool, the NPS module comprising:
a mandrel positionable around a slick joint of the run-in tool and having one or more fluid pathways that balance pressure uphole of the mandrel and downhole of the mandrel when the NPS module is positioned within the borehole;
a lug assembly positionable around the slick joint and extending at least partially through the mandrel, a lug of the lug assembly extendable through a port in the liner hanger to prevent setting of the liner hanger when the lug assembly is in a run-in position;
a release sleeve positionable around the slick joint and coupled to the lug assembly, the release sleeve operable to shift the lug assembly from a run-in position to an intermediate position, the intermediate position allowing the liner hanger to be set; and
a retention mechanism operable to prevent the lug assembly from shifting from the intermediate position to a retracted position until run-in tool is pulled uphole.
